Embodiment 1
[0115] Batch preparation of 23 titanium matrix composite bars of different compositions with a diameter of 30 mm:
[0116] 900g of TC4, TA15, pure Ti and TC18 powder were used, respectively, with different contents of TiB 2 , C powder and TiB 2 +C is used for low-energy ball milling and powder mixing, and the designed composite material system is shown in Table 1.
[0117] Table 1
[0118]
[0119] A 23-hole porous mold with a diameter of 30 mm was designed. The porous mold was placed on the first indenter, and graphite blocks with a diameter of 30 mm and a height of 20 mm were placed in each through hole, and graphite blocks with a size of 350 × 95 mm were placed The paper roll is placed in the through hole, and the ball-milled powder is then loaded into the porous mold. Put a carbon / carbon mold protector on the outside of the porous mold. Protrusions with a diameter of 30 mm and a height of 150 mm were placed on the porous mold. A second indenter with a diameter of 4...
